President Trump's former 2016 campaign chairman Paul Manafort and Rick Gates, Manafort's former business associate, have been indicted by a federal grand jury in the investigation into Russian meddling in the U.S. election, according to unsealed documents released Monday.

Who is Paul Manafort?

Paul Manafort is a lobbyist and political consultant who worked across numerous presidential campaigns, most recently stepping in as chairman of Donald Trump's successful 2016 presidential campaign. Manafort came on board the Trump campaign in March 2016, but resigned in August 2016 as his connections to former Ukrainian president Viktor Yanukovych came under press scrutiny.

Manafort was a founding partner of Black, Manafort & Stone, a lobbying firm he set up in 1980 with Roger Stone, another on/off Trump advisor and notorious political operative. The firm lobbied in Washington D.C. on behalf of leaders like Congolese strongman Mobutu Sese Seko, Filipine president Ferdinand Marcos, among others.
